STEVAL-ISA110V112 V/12 W wide range non-isolated flyback based on the VIPER26LN
The STEVAL-ISA110V1 demonstration board is a 12 V-1 A power supply set in non-isolated flyback topology using the VIPER26LN, a new offline high-voltage converter by STMicroelectronics.
The features of the device include an 800 V avalanche-rugged power section, PWM operation at 60 kHz with frequency jittering for lower EMI, current limiting with adjustable set point, onboard soft-start, a safe auto-restart after a fault condition, and low standby power.
Protection features include thermal shutdown with hysteresis, delayed overload protection, and open loop failure protection.
- Universal input mains range:
- input voltage 90 - 264 VAC
- frequency 45 - 65 Hz
- Single output voltage: 12 V @ 1 A continuous operation
- Standby mains consumption: < 30 mW @ 265 VAC
- Average efficiency: > 85%
- Fully protected against faults (overload, feedback disconnection and overheating)
- EMI: according to EN55022-Class-B
